Thread: .003 oversize rocker adjusters....

Tweet

Anyone use these and did you have any problems threading them in? I'm in the process of replacing some of my adjusters with the .003 oversise ones and can't get them to thread in correctly. The stock ones are a loose fit on some rockers and figure the oversize adjusters would be a plug and play deal. No such luck. I have the right adjusters and the ones I'm replacing are indeed the OEM stockers. I first thought I had some bastard rockers but they check out ok. I've even taken the rocker arm off and apart to get a better bite and leverage on them. I can get them finger tight and start a thread or two before pulling crooked and start to crossthread. They just seem to be too big. Anyone know of a source for .002 adjusters??? These have me stumped. G.

Never have tried the oversize, G. I do have a set of aftermarket shafts and aluminum rockers I scored on eBay for real cheap awhile back. Got the stockers around here someplace, will check out the adjusters to see if they are any good.....Now all I got to do is find them!!!!

Good morning Dave and thanks for the fast reply. Yes please let me know what you find. G.

Denny thanks for the info. My buddy works at a machine shop and he's looking into this for me. Funny as some of the stockers are way loose but the .003's are too big to thread correctly. I had thought there was a .002 adjuster but no such luck and looking into the taps. I have a practice rocker to see how the tap works and hoping for the best. If all else fails I'll get the Crane adjsuters and re-tap the rockers to fit. And I thought this would be an easy fix.....

I'll keep you posted. I've talked with a few guys that have installed these no problem. Just took out the old and installed the new. I guess mine are somewhere in between but a few are quite loose and would no way hold adjustment as is. The stock tap is a 7/16 x 20 special form thread with a pitched top diameter from .4025-.3978. Should have seen the blank expressions on the faces of the guys at Autozone when I asked for a .001 oversize tap. I knew then I needed professional help LOL. G.
